Depending on the location and the electrical demand, a combination of corrosion and heat can cause a momentary break on either of two electrical circuits at the bulkhead connector (21 or 29). if these circuits fail, the ignition, parking light, fuel pump, fuse panels and the secondary electrical braking system will lose power.

Consequence Summary

Loss of power to the secondary electrical braking system can result in increased stopping distances and possible vehicle accident.

Corrective Summary

Power from the battery will be run directly to the stop lamp switch and the ignition switch. this will eliminate the bulkhead connection for the ignition circuit and back-up brake circuit as well as dividing up the load on the two questionable circuits.
